The temple at Cape Sounion, Attica, was a venue where mariners, and also entire cities or states, could propitiate Poseidon by making animal sacrifice or leaving gifts. The temple of Poseidon was constructed in 444–440 BC, over the ruins of a temple dating from the Archaic period. It is perched above the sea at a height of almost 60 metres (200 ft). The design of the temple is a typical hexastyle, i.e., it had a front portico with six columns. Only some columns of the Sounion temple stand today, but when intact it would have closely resembled the contemporary and well-preserved Temple of Hephaestus beneath the Acropolis, which may have been designed by the same architect. As with all Greek temples, the Poseidon building was rectangular, with a colonnade on all four sides. The total number of original columns was 34: 15 columns still stand today. The columns are of the Doric Order. They were made of locally quarried white marble.
